An engineers square, also known as a Machinist square, is a handheld marking and checking tool used to assess angles and mark straight lines. Made up of two straight pieces (stock & blade) which work together to create a right angle at exactly 90°. The two pieces of the engineer square intercept at the end creating a precision L shaped tool, these two pieces can vary in length for both small and large working environments. The purpose of an engineering square is to check that the angles are correct with whatever project or piece of work you are working on and to mark lines with the angles to make sure everything is correct and in line.
